If we consider the Voltage change starting at Point P and going all the way around the circuit loop back to Point P, what is the total AV? I AV = +6.0 Volts B lAV = +1.5 Volts C AV = -4.5 Volts AV = 0.0 Volts not enough information The circuit shown contains an ideal battery When the switch is closed, what happens to the current i1 through resistor R1? .goes up 3 goes down c Stays unchanged .Not sure Now consider the same circuit with a real battery (with internal resistance r) When the switch is closed, what happens to the current i1 through resistor R1? . goes up B goes down c I Stays unchanged I Not sure
