Question 1 of 10
1. Question
How the charge will flow?
Correct
Charge fill will flow if and only if potential difference is applied.
Incorrect
Charge fill will flow if and only if potential difference is applied.

Question 2 of 10
2. Question
If length of a conductor and it’s radius is increased twice, how the resistance will change?
Correct
Incorrect

Question 3 of 10
3. Question
The potential difference applied is directly proportional to current only if
Correct
According to OHMs Law, the potential difference is directly proportional to current if temperature is constant.
Incorrect
According to OHMs Law, the potential difference is directly proportional to current if temperature is constant.

Question 4 of 10
4. Question
Equivalent resistance of 4 4Ω resistances in parallel is
Correct
The equivalent resistance R, of 4 4Ω resistance in parallel is given as
Incorrect
The equivalent resistance R, of 4 4Ω resistance in parallel is given as

Question 5 of 10
5. Question
Which of the following conditions represent more resistance at constant temp?
Correct
Since V=IR by the OHMS LAW,I=V/R, so slope of the graph is 1/R, more the slope more the value of 1/R, and hence less the value of R and vice versa. The slope of red line is less than yellow, therefor red line will have more resistance.

Question 8 of 10
8. Question
A resistor of length l is connected to a battery and current I is flowing through it. If it is divided into 3 parts by length, and all are having same cross sectional area are connected in series with the same battery, the current flowing through them will be?
Correct
Net resistance will be same as the previous case because the net length and cross sectional area will not change.
Incorrect
Net resistance will be same as the previous case because the net length and cross sectional area will not change.

Question 9 of 10
9. Question
Two resistances R_{1} and R_{2} are connected with a cell in parallel. Find the ratio of current flowing through R_{1} to the current flowing through R_{2}.
