Determine the ammeter reading if the voltmeter shows a voltage of 12 V, the resistance of the resistor is 30 Ohm
| March 19, 2021 | education
Task data: U (voltage value according to voltmeter readings) = 12 V; R (resistor resistance) = 30 ohms.
The value of the current in the circuit, which the ammeter will show, can be calculated by the formula: I = U / R.
Calculation: I = 12/30 = 0.4 A.
Answer: The ammeter should show that a current of 0.4 A. flows through the circuit.
