Question #51019

Two resistances

2Ω

and

3Ω

are in parallel. The combination is in series with

1.5Ω

resistance and a power supply of voltage V. There is a current of 3A through the

2Ω

resistance. What are the values of the current I delivered by, and the voltage V across the power supply?

Two wires P ad Q, each of the same length and same material, are connected in parallel to a battery. The diameter of P is half that of Q. What fraction of the total current passes through P?

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

, 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

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
