A circuit consists of three identical lamps connected to a baterry with a switch, shown below.What happens when the switch is closed.
a)potential difference across C
b)Current of C
c)resistance in C
d)total power dissispated in the circuit

Well apparently, the switch would close off the current to C and therefore no voltage, current or resistance according to V=IR
Power dissipated would be V^2/2R

Edit: Yea, I'm not sure how switches close off current from circuit elements too..

I'll have a guess:

Potential difference across C will decrease.

Current a C will be smaller because current has now two paths to take and it is also the path with more resistance.

I don't think resistance in C changes

Since we closed the switch and current takes a different path, resistance would be smaller (2 bulbs) and so power dissipated will be bigger.
