-1 Two loop rules and a point rule are created for a simple circuit:
10 - 10I2 - 20I1 = 0
10 - 5I3 - 20I1 = 0
I1 = I2 + I3
I1 represents the current coming from the battery. Assume that all currents are positive. What is the equivalent resistance of the circuit?
A. 10.0 ? B. 35.0 ? C. 12.7 ? D. 23.3 ?
1.2 For the situation described by the equations given in the previous question, which resistor would have the greatest voltage?
A. The 10 ? resistor B. The 5 ? resistor C. The 20 ? resistor D. Each resistor has equal voltage
-1.3 A simple circuit consists of a 10 volt battery and three resistors in series. Two of the resistors have resistance R and one has resistance 3R. If the current in the circuit is 2 A, determine the value of R.
A. 1 ? B. 2 ? C. 0.5 ? D. 3 ?
-1.4 A simple circuit consists of a battery (?) and two identical resistors (R). Would the power dissipated in one of the resistors be larger if the resistors were connected in series or in parallel?
A. Series B. Parallel C. Both would be the same D. Can't determine unless values are given
