Four resistors are wired in series: R1 = 30Ω, R2 = 20Ω, R3 = 60Ω, and R4 = 60Ω. If the total voltage is 70V, what is the voltage (in volts) across the R1 resistor?

Step 1
Total resistance (R_total) = R1 + R2 + R3 + R4 = 30Ω + 20Ω + 60Ω + 60Ω = 170Ω Show more…

A circuit consists of a power supply and two resistors R1 and R2 connected in series. A voltmeter is placed to measure the voltage across resistor R1 The voltmeter reads V1 = 3.2 V, and the values of the resistors are R1 = 3.2 kOhm and R2 = 820 Ohm. What is the current through R2? Units may be supplied as "A" or as "mA".
