The formula for calculating power delivered by a battery in a simple RL circuit is P = I^2R, where P is power in watts, I is current in amps, and R is resistance in ohms.
The power delivered by a battery in a simple RL circuit initially starts at its maximum value, and gradually decreases as the inductor builds up a magnetic field. Once the magnetic field is fully established, the power delivered by the battery reaches zero.
The power delivered by a battery in a simple RL circuit is affected by the resistance of the circuit, the current flowing through the circuit, and the inductance of the inductor. Other factors such as temperature and the type of battery used can also affect the power delivered.
If the resistance in a simple RL circuit is increased, the power delivered by the battery will decrease as the current flowing through the circuit decreases. This is because the higher resistance creates a larger voltage drop, reducing the amount of current that can flow through the circuit.
No, the power delivered by a battery in a simple RL circuit can never be negative. This is because the power is always defined as a positive value, representing the rate at which energy is delivered to the circuit. Negative power would indicate that energy is being taken away from the circuit, which is not possible in this scenario.
