Sources of error: The resistance of the wire could vary overtime as the current flows through and heats the wire up, affecting the value for I, causing the value of I to be inaccurate.
Comments: 1/R is directly proportional to I Source of error: The wires have resistance and this adds to the total resistance, leading in accuracy of the reading R
Comments: 1/R is directly proportional to I. Source of error: The wires have resistance, and this adds up to the total resistance, leading to inaccuracy of the reading R
Comments: 1/R is directly proportional to I. Source of error: The wires have resistance, which is ignored for our calculations. This affects the actual value of the reading R.
sources of error: The resistance of the wire increases as the current flows through and causes the wire to heat up, which will affect the value of I, making it inaccurate.
C=0 V=9 Comments: 1/R is directly proportional to I. Source of Error: The resistance of the wires is included in the total resistance, which may lead to inaccurate measurements of R.
comments: 1/R is directly proportional to I. sources of error: The difference in resistance of the wires. The heating of wires cause its resistance to change,thus leading to the inaccuracy of measurement of R.
Karyn Gunawan, 4 Hum value of c: 0 value of v: 9 comments: 1/R and I are directly proportional. sources: the resistor gets hot over time, converting electrical energy into heat energy. Thus affecting the reading of the ammeter, affecting the accuracy of the results.
C = 0 V = 9 Comments : 1/R is directly proportional to I. Source of Error : The wire gets hot after some time. The resistance of wire will change hence the current will not be consistent.
Source of error:As electricity passes through the wires, the wires heat up, and as a result, the resistance of the wires will change, hence affecting the values of l.
Comment:I/R and I are directly proportional to each other.
Sources of error:Some electrical energy may be converted to other forms of energy, such as heat energy to the surrounding, hence causing the source of energy(battery) to have less Electomotive force, which will in turn cause the charges (electrons) to flow even more slowly, not only at the resistor, but at the wires too. Therefore this will cause the current to be further reduced.
Source of Error:The wire's resistance would add up with the resistor's resistance,thus causing I to be inaccurate. Furthermore,the wires may heat up and vary in resistance.
Audrey Koo, 4 Humility C= 0 V= 9 Comment:1/R is directly proportionate to I. Sources: After a while, the wires become hot due to the electricity passing through the wires. Therefore, the resistance of the wire will change, making the values of I inaccurate.
Source of error: There might be resistance in the wire which will increase the resistance in the circuit, hence affecting the value of I, the ampere obtain causing an inaccurate measurement of I.
Source of error: The wires already have resistance ,it will cause the resistance of I to be inaccurate as the resistance of the wires are not included in calculation of I.
sources of error: the wires have some resistance i think, then the whole circuit will have more total resistance.causing the value of I to be inaccurate. affecting the accuracy of I
Jacqueline Ng, 4 Respect Value of C: 0 Value of V: 9 comment: 1/R is directly proportional to I. Source of error: The resistance of the wire can cause the recordings taken to be inaccurate.
Value of C : 0 Value of V : 9 Comment : I is directly proportional to 1/R Source of error : The electrical wires used in the experiment, although good conductors, have electrical resistance which adds to the total electrical resistance. This will result in an inaccurate readings as the resistance is more than the stated value of the resistor.
Value of V: 9 Value of C: 0 Comment: 1/R is directly proportional to I. Source of error: The wires will heat up due to the electricity passing through it. Therefore, the resistance of the wires may change, causinng the values of I to be inaccurate.
c=0, v=9 Comment: 1/R is directly proportional to I. Sources of error: wires have resistance which may cause the recording of results to be inaccurate.
I/R is directly proportional to I. c=0, v=9 Sources of error: There is already resistance in the wires, so this resistance is added to our total resistance, thus leading to the inaccurate result of R.

Eh guys. If you sub in the values for the equation
ReplyDeleteI = V/R + C
Subsitute in v=9 and c=0, it will result in
I = 9/R
But let R be 4.5
I = 9/4.5
= 2
This does not corresponds to the value of 0.5
Flawed?
