P is not a Roman numeral. IV is the Roman numeral for 4.
V = IR, so an alternate would be P = I2R
Why is the i written I in iv? why is Iv written like that instead of iv.
iv or IV = 4
IV = 4
IV is no. 4
P = I^2 R = IV = v^2 / R , Where P is power, I is current, R is resistance, and V is voltage. Given voltage and current, power = current * voltage, or P = IV.
P=IV and V=IR so subbing V in P=IV you get the equation to use which is P=I2R So rearrange this to get R as the subject you get R= P/ I2 so R= 1000/5 2 = 1000/25= 40 Ohms

I, II, III, and IV Tammy :p

P=IV Power=current x voltage

V = IR, so an alternate would be P = I2R
Power can be calculated various ways: P = IV P = I2R P = V2 R To calculate Energy, simply multiply by the time. P = Power I = Current V = Voltage R = Resistance
A watt is a unit of power, and power is given by P = IV where P is power, I is current and V is voltage. Therefore, P = IV = (7.8A)*(110V) = 858A*V = 858W
