# Question

Draw the circuit diagrams indicating the correct placement for the voltmeter in the following situations. (Use a circle with an “V” in it to represent the voltmeter.)

(a) Three resistors are wired in parallel and you want to measure the total voltage across all of them with just one measurement.

(b) Three resistors are wired in parallel and you want to measure the voltage across just one of them with just one measurement.

(c) Three resistors are wired in series and you want to measure the total voltage across them.

(d) Three resistors are wired in series and you want to measure the voltage across just one of them.

Are the joule heating rates in resistors in parallel generally the same? If not, under what circumstance(s) could they be the same? Three resistors that have values of 10 Ω, 20 Ω, and 30 Ω are to be connected. (a) How should you connect them to get the maximum equivalent resistance, and what is this maximum value? (b) How should you connect them ...The terminals of a 6.0-V battery are connected to points A and B in Fig. 18.29. (a) How much current is in each resistor? (b) How much power is delivered to each?
