The formula P = I^2R relates power (P), current (I), and resistance (R), indicating the power dissipated in a resistor. On the other hand, the formula P = V^2/R relates power (P), voltage (V), and resistance (R), representing the power dissipated across a resistor. The former formula deals with power in terms of current, while the latter formula expresses power in terms of voltage.

Q: What is the difference between P I2R or P V 2R?

Nothing. If I is current, V is voltage, and R is resistance, then V=I*R and V*I=P, where P is power.

Electrical power is measured in watts. The formulas for power dissipated by a resistor are:

* P = V × I * P = V² / R

* P = I² × R P is power, V is voltage, I is current, R is resistance.

P = V x I

I = P/V = 342/11.6 = 29.483 Amperes (rounded)
