Final answer:
A 6-volt battery provides a potential difference of 6 volts across its terminals, which determines the voltage available in a circuit. The actual voltage may be different if internal resistance or series connections come into play. Calculations using this voltage include finding current through resistors and power dissipated in a circuit.
Explanation:
A 6-volt (V) battery maintains an electrical potential difference (voltage) of 6 volts across its terminals. The potential difference is the energy difference per charge between two points in an electric circuit. When batteries are discussed, their nominal voltage (6 V in this case) is the potential difference they are designed to provide when no current is flowing through the battery's internal resistance. If batteries are connected in series, their voltages add up. For example, connecting a 3 V battery in series with a 6 V battery would result in a total potential difference of 9 V (assuming positive to negative terminal connection).
When a resistor is connected across a battery, as in the case of a 24-ohm resistor connected across a 6 V battery, the current in the circuit can be calculated using Ohm's Law, which is I = V/R. Therefore, the current would be 0.25 amperes (A) in this scenario.
The power dissipated by resistors in a circuit powered by a 6 V battery can be found using the formula P = VI, where V is the potential difference across the resistor and I is the current through it. It's important to consider any internal resistance when analyzing the potential difference supplied by the battery.
