See Sample Problem \(A\). A length of wire is cut into five equal pieces. If each piece has a resistance of \(0.15 \Omega,\) what was the resistance of the original length of wire?
Two identical parallel-wired strings of 25 bulbs are connected to each other in series. If the equivalent resistance of the combination is \(150.0 \Omega\) and it is connected across a potential difference of \(120.0 \mathrm{V}\) what is the resistance of each individual bulb?
A \(30.0 \Omega\) resistor is connected in parallel to a \(15.0 \Omega\) resistor. These are joined in series to a \(5.00 \Omega\) resistor and a source with a potential difference of \(30.0 \mathrm{V}\) a. Draw a schematic diagram for this circuit. b. Calculate the equivalent resistance. c. Calculate the current in each resistor. d. Calculate the potential difference across each resistor.
Review Questions If four resistors in a circuit are in parallel, which of the following is the same for the resistors in the circuit? a. potential difference across the resistors b. current in the resistors
See Sample Problem \(B\). An \(18.0 \Omega\) resistor, \(9.00 \Omega\) resistor, and \(6.00 \Omega\) resistor are connected in parallel across a 12 V battery. Determine the following: a. the equivalent resistance for the circuit b. the current delivered by the battery
