How do you calculate the power output of a battery? The formula for the power output P of a battery is P=VI−RI2 P = V I − R I 2, where V is the electromotive force in volts, R is the resistance in ohms, and I is the current in amperes. Find the current that corresponds to a maximum value of P in a battery for which V = 12 volts and R = 0.5
The energy output of a battery is the total amount of energy it can provide over its lifetime. On the other hand, the power output of a battery is the rate at which it can deliver energy at a given moment. This is typically
The energy output of a battery is the total amount of energy it can provide over its lifetime. On the other hand, the power output of a battery is the rate at which it can deliver energy at a given moment. This is typically measured in watts (W) or amps (A) and can vary depending on the type and size of the battery.

The voltage level of the battery determines the maximum electrical power which can be delivered continuously. Power P [W] is the product between voltage U [V] and current I [A]: [P = U cdot I tag{1}] The higher the current, the bigger the diameter of the high voltage wires and the higher the thermal losses. For this reason, the current

1) The battery has a maximum power it can provide. For example, if this power is P = 100 W, then since P = RI^2 the current will be I = (P/R)^0.5 = 31.6 amps and the voltage V = RI = 3.16 V. 2) The battery has a maximum current it can provide. For example, if this current is I = 5 A, then V = RI = 0.5 V.
