The ____ dissipated in a resistor?

Question

the ___ dissipated in a resistor is proportional to the square of the current that passes through it and to the resistance.

a- voltage

b- power

c- current

d- kinetic energy

Answer 1

The answer is b, Power = I(2) x R ; this means that the power that is released by the resistor is expressed as the amount of current squared multiplied by the resistance.

Answer 2

power...

Answer 3

P=I^2R

that's the formula so, power

Answer 4

Power.

Power, P, is given as:

P = I^2 * R

Note that the relationship, V = IR can be used to redefine power as:

P = I * V
