There is a single loop circuit with two reversible emfs (E1= 12 V andE2= 6 V) and tworesistors (R1= 4 Ω andR2= 8.0 Ω).(Reversible in this context means they can supply orabsorb energy.) Consider the loop to be rectangular as usual:R1is on the top segment;R2ison the right segment;E1is on the bottom segment with positive terminal aimed right;E2is onthe left segment with positive terminal aimed up.a) Draw a schematic circuit diagram with correct symbols for the components.b) What is the current in the circuit with direction specified?c) What is the power dissipated in each resistor?d) What is the power of each battery and is it emitted or absorbed?028 qfull 00530 2 5 0 moderate thinking: power in simple loopExtra keywords:with a variable resistor6. You have a single loop circuit with a battery of fixed emfEand two resistors (in series of course)with resistancesR1andR. The resistorRis variable.
