In a simple electric circuit, Ohm's law states that V = IR, where V is the voltage in volts, I is the current in amperes, and R is the resistance in ohms. Assume that, as the battery wears out, the voltage decreases at 0.04 volts per second and, as the resistor heats up, the resistance is increasing at 0.02 ohms per second. When the resistance is 100 ohms and the current is 0.01 amperes, at what rate is the current changing? amperes per second

Concept explainers

Ohm's law

Ohm’s law is a prominent concept in physics and electronics. It gives the relation between the current and the voltage. It is used to analyze and construct electrical circuits. Ohm's law states that the voltage across a conductor is directly proportional to the current flowing through it.

Path of Least Resistance

In a series of alternate pathways, the direction of least resistance is the actual or metaphorical route that offers the least resistance to forwarding motion by a given individual or body.

Question

In a simple electric circuit, Ohm's law states that V = IR, where V is the voltage in volts, I is the
current in amperes, and R is the resistance in ohms. Assume that, as the battery wears out, the voltage
decreases at 0.04 volts per second and, as the resistor heats up, the resistance is increasing at 0.02
ohms per second. When the resistance is 100 ohms and the current is 0.01 amperes, at what rate is the
current changing?
amperes per second
