Question
In the context of electrical circuits, Ohm's law describes the
relationship between the voltage, V, across a resistor, the electrical
current, I, passing through the resistor, and a quantity, R, known as
the resistance. The law can be written as follows:
V = IR
Voltage is typically measured in volts, current is measured in
amperes (or amps), and resistance is measured in ohms, where 1
ohm = 1 volt/amp. In a circuit with variable resistance, the
quantities V, I, and R might all depend on time.
Suppose that the voltage across the resistor is held constant at 20
volts, while the resistance is steadily increased at a rate of 0.62
ohms/sec. At what rate is the current changing when the resistance
reaches 10 ohms?
You may leave off the units (amps/sec).
Hint: You may fırst need to determine the current through the
resister at the moment when resistance reaches 10 ohms.
