Question
1) What happens to the current through point 3? Explain.
stays the same because the wire has no resistance and total resistance in the circuit is not changed.
increases because connecting a wire from 1 to 4 decreases the total resistance in the circuit resulting in the increase in current in the whole circuit.
decreases, because the wire through 1 and 4 disconnects the bulb B from the battery. Before, all the current through the circuit went through point 3. Now, the current through C goes through the new wire instead.
What happens to the following quantities?
The potential difference across B
The potential difference across C
The potential difference between points 1 and 5
decreases to zero
nothing happens
equals to the potential difference of the battery
