Consider the following circuit: 3 Ω 192 5Ω 292 492 12 V (a) Carefully identify series and parallel combinations. Make sure that you use the connections, not the layout on the page to decide - you should have done some of this already as part of a prep assignment. (b) Find the equivalent resistance of the circuit. (c) Find the current through and power dissipated in each resistor (d) Find the power provided by the battery. Confirm that the total power dissipated by the resistors equals the power from the battery. You may have a rounding error in the least significant digit of plus or minus one; that is ok, but you should not be off by much more than that. (e) What would be the power provided by the battery if the 5 Ohm resistor were replaced with a 0 Ohm resistor (i.e. if we "shorted out" the 5 Ohm resistor)? What would be the power provided by the battery if the 5 Ohm resistor were replaced with an infinite Ohm resistor (i.e. if we disconnected the resistor from the circuit or replaced it with an open switch)? Use these answers to check your work.

Consider the following circuit:
3 Ω
192
592
292
492
12 V
(a) Carefully identify series and parallel combinations. Make sure that you use the connections, not
the layout on the page to decide - you should have done some of this already as part of a prep
assignment.
(b) Find the equivalent resistance of the circuit.
(c) Find the current through and power dissipated in each resistor
(d) Find the power provided by the battery. Confirm that the total power dissipated by the resistors
equals the power from the battery. You may have a rounding error in the least significant digit
of plus or minus one; that is ok, but you should not be off by much more than that.
(e) What would be the power provided by the battery if the 5 Ohm resistor were replaced with
a 0 Ohm resistor (i.e. if we "shorted out" the 5 Ohm resistor)? What would be the power
provided by the battery if the 5 Ohm resistor were replaced with an infinite Ohm resistor (i.e.
if we disconnected the resistor from the circuit or replaced it with an open switch)? Use these
answers to check your work.
