The formula for calculating current supplied by a battery is I = V/R, where I is the current in amperes (A), V is the voltage in volts (V), and R is the resistance in ohms (Ω).
The voltage of a battery can be determined by using a voltmeter, which measures the potential difference between the positive and negative terminals of the battery. Alternatively, you can also refer to the label or specifications of the battery, which usually indicate the voltage.
The current supplied by a battery is affected by the voltage and resistance in the circuit. Higher voltage will result in a higher current, while higher resistance will result in a lower current. The type and condition of the battery can also affect the current supplied.
The resistance in a circuit can be calculated using Ohm's law, R = V/I, where R is the resistance in ohms (Ω), V is the voltage in volts (V), and I is the current in amperes (A). Alternatively, you can also use a multimeter to measure the resistance in a circuit.
Yes, the current supplied by a battery can be changed by adjusting the resistance in the circuit. Increasing the resistance will result in a lower current, while decreasing the resistance will result in a higher current. However, the voltage of the battery will remain constant unless it is changed or the battery depletes over time.
