choices
series
parallel
series-parallel
Assume there are 10 light bulbs that can be connected in series and 10 light bulbs that can be connected in parallel. Each bulb is rated 40 W. If the voltage at the plug is 220 V for both series and parallel connections, calculate the current through each bulb for both cases. Also find the voltage across each bulb.
Three resistors of 12Ω , 52Ω and 72 Ω are connected in parallel. If the total current is 100 A, how much current will pass through each resistor?
