Ω is connected to a battery with a voltage of 10 V. Calculate the current through the meter movement when it is connected to the battery.
To calculate the current through the meter movement, we can use Ohm's Law. Ohm's Law states that the current (I) flowing through a circuit is equal to the voltage (V) divided by the resistance (R):
I = V / R
In this case, the voltage (V) is 10 V and the resistance (R) is the internal resistance of the meter movement, which is 100 Ω. Plugging these values into the equation, we get:
I = 10 V / 100 Ω
I = 0.1 A
So, the current through the meter movement when it is connected to the battery is 0.1 A or 100 mA.
