... a magnetic field. The larger the current, the larger the torque → the larger the deflection. Internal resistance of a galvanometer ≈ 60 Ω. This makes it hard to measure the current in a circuit where the resistance of the circuit is 60 Ω. Example: A circuit with 3 V battery and a 3 Ω resistor. Fro ...

When you do work to lift a ball from the ground, you give the ball a different type of energy, called potential energy. (kindly listen to the reporter’s explanation…) You can also give some objects potential energy by c ...
