In an electric circuit, the larger the diameter of the wire, the ____________________ the electrical resistance to current flow.

Which of the following is a formula for the power dissipated by a resistor? Let V be the voltage across the resistor, / be the current through the resistor, and R is the value of the resistance of the resistor. PIR V/R O PR

What is the voltage drop across R in the circuit below if the shown resistances have the following values: R1=10 N R2=10 N R3=10 N and the voltage provided by the voltage source is 13 volts. R1 R2 R3 adap fo V

a) If the current in this circuit is 3 A, what must be the value of R3? b) What is the voltage drop across the 2 ohm resistor? c) What is the voltage drop across the 3 ohm resistor. d) What is the power used in the circuit in amps?

In the circuit shown, the potential difference VA = VB = 46.0 V and the resistance R1 = R2 = R3 = R4 = 155 Ohms. The arrows for currents IA and IB indicate the direction of positive current flow. The arrows do not necessarily indicate the direction that the current flows.  Find IA Find IB

The diagram below shows a circuit where R1 = 5 N, R2 = 7 N, R3=1 N, Vị = 8 Volts, V2 = 5 Volts, and V3 = 7 Volts. What is the value of I1? In solving this problem, initially pick the current directions as shown. If the actual current turns out to be in the opposite direction, then your answer will be negative. If you get a negative number, enter it as negative. V1 R3 13 R1 I R2 V3 V2
