Three resistors are connected in series across a 19-V power supply. If the potential drop across resistors 1 and 2 are 3.2 volts and 3.0 volts, what is the potential drop (in volts) across resistor 3?
A 224-O and a 211-O resistor are connected in series across an unspecified power supply. If the current through the 224-O resistor is 0.49 A, what is the current (in A) through the 211-O resistor?
A battery supplies 0.77 A to three parallel resistors. The current through the first resistor is 0.27 A and the current through the second resistor is 0.21 A. What is the current (in A) through the third resistor?
A 167 O resistor and a 114 O resistor are both connected in parallel across a power supply. If the potential drop across the 167 O resistor is 19 V, what is the potential drop (in V) across the 114 O resistor?
