Homework Statement
1) a complete circuit consists of a 12.0 V battery with a 4.50 ohm resistor and switch. the internal resistance of the battery is 0.30 ohms when switch is open. what does the voltmeter read when placed:
a. across the terminal of the battery when the switch is open
b...
Hey can i get your thoughts on this one? i can't seem to figure out, its an internal resistance and electromotive force problems
