Question
The student chooses a fixed resistor with a resistance of 5 kΩ. The reading on the ammeter is 0.8 mA. (i) State the equation linking voltage, current and resistance.
Solution
The equation linking voltage, current, and resistance is Ohm's Law, which is stated as:
V = I * R
Where: V is the voltage (in volts), I is the current (in amperes), and R is the resistance (in ohms).
