Question

A formula for electrical circuits states that E=P/\I where E represents the force in volts, P represents power in watts, and I represents current in amps. Solve this formula for I. Then find I when the force E = 3.6 volts and the power P = 45 watts.

Answer 1

`I=12.5` amp

Explanation:

The formula is,

`E=(P)/(I)`

where,

E = Electromotive force in volts,

P = Power in watts,

I = Current in amps.

Given values are,

E = 3.6 volts,

P = 45 watts,

I = ??

Putting the values,

`\Rightarrow 3.6=(45)/(I)`

`\Rightarrow I=(45)/(3.6)=12.5` amp
