Two 7.4 resistors are connected in parallel, as are two 4.9 resistors. These two combinations are then connected in series in a circuit with a 11 battery.
What is the current in each resistor?
What is the voltage across each resistor?
I will start you: the two 4.9 in parallel is 4.9/2 ohms. Now add that to the two 7.9 in parallel, and ...
Three 10-Ohm resistors are connected in series to a 30-V battery. If the current in the circuit is 1 A, the total resistance in the circuit is _____ ohms.
