Question #61536

10 In an experiment to determine the relationship between the current I through a piece of tungsten wire and the potential difference V across it, the theoretical relationship used was

I=kVn

I=kVn

, where k and n are constants which may be obtained from a straight line graph of the form y = mx + c, the symbols having their usual meaning. The corresponding linear equation for this experiment is ----------

I = nV + k

4I=nV2+k

4I=nV2+k

I=expVn+k

I=expVn+k

logI = nlogV + logk

11 A current of 0.5A flowing through a wire produces 21J of heat in 1/2 min. The resistance of the wire is ----------- ohms to 1 place of decimal

2.8Ω

2.8Ω

3.2Ω

3.2Ω

1.4Ω

1.4Ω

4.6Ω

4.6Ω

12 Which of the following is not true about internal resistance.

It is the opposition to the flow of current within a battery

I=E/r+R

is valid

It is equal to emf

Internal resistance is not the same as voltage
