How to get the current if the given is the power and electric potential only?...?

Question

please show me the formula

Answer 1

power = potential * current

this is easily derived. Power is in watts which are joules/second. potential is volts, current is amps which are coulombs/second. As one joule = one volt.coulomb the units balance to joules/second = joules/second.

Thus,

current = power/potential.

Assuming international units.

Answer 2

Potential is measured in volts.

Current is measured in amps, and power in watts.

Watts = Volts x Amps

so

Amps (current) = Watts (power) / Volts (potential)

Answer 3

P=IV

I=P/V

where:

P=Power

V=Electric potential

I=Current
