- In the figure resistor 1 = 126 2, resistor 2 = 81 N, and the ideal batteries have emfs ɛ1 E2 = 5 volts, and ɛ3 = 7 volts. Find the current through resistor 1. = 29 volts, Round off answer up to 3 decimal places. Consider absolute value. Include the unit (A for ampere, V for volt and ohm for ohm). Rz RI wwThree resistors are connected in parallel. The resistances are each worth R1 = 2 ohms, R2 = 1 ohm and R3 = 2 ohms. If the resistance circuit is connected to a voltage of 12 volts, calculate the total current and the current flowing in the 1 ohm resistance. a. The magnitude of the total current = 14 A; current strength at R2 = 12 Ab. The magnitude of the total current = 24 A; current strength at R2 = 12 Ac. The magnitude of the total current = 18 A; current strength at R2 = 14 Ad. The magnitude of the total current = 20 A; current strength at R2 = 14 AIf a brass wire is 4 cm long with a diameter of 1.3 cm, calculate its resistance. Determine the voltage drop over the brass wire for a 1.0 A current in the circuit.

The potential difference across the battery is 40.0 volts, and it supplies a current of 5.00 amperes to the circuit. There is a current of of 2.70 amperes flowing through R1. Resistor R2 has a resistance of 5.50 ohms. What is the resistance of R3? Answer in ohms to two decimal places, but do not include units in your answer.The conductance G of an object is defined as the reciprocal of the resistance R; that is, G = 1/R. The unit of con- ductance is a mho (= ohm'), which is also called the siemens (S). What is the conductance (in siemens) of an object that draws 440 mA of current at 3.0 V?
