Answer:
Voltage = 9.6 Volts
Explanation:
Given the following data;
Resistance = 24Ω
Current = 0.4A
To find the voltage of the battery;
Ohm's law states that at constant temperature, the current flowing in an electrical circuit is directly proportional to the voltage applied across the two points and inversely proportional to the resistance in the electrical circuit.
Mathematically, Ohm's law is given by the formula;
[tex] V = current * resistance [/tex]
Substituting into the formula, we have;
Voltage = 0.4 * 24
Voltage = 9.6 Volts
Therefore, the battery voltage must be 9.6 volts
