Three resistors, 1.1 Q 9.0 2 and 3.2 Q are wired in series with a power source of 7.3 volts. Calculate the potential difference in Volts across the 1.1 Q resistor. Use 2 significant figures in your answer. Hint: The same current must go through all three resistors, so the equivalent resistance Reg ( the sum of the resistances) can be used with Ohm's Law to find the current. The current, must then produce a voltage drop I * R1 across the first resistor. Answer:

Question

The resistance of gold wire used in circuits is usually negligible compared to the components in the circuit, and can be ignored. For long, thin wires, this is no longer true.

Calculate the resistance, in ohms, of a length of gold wire, 46.6 cm long, with a cross sectional area of 2.5 mm2. The resistivity of gold is 2.35×10-8 Ω.m. Use 2 significant figures in your answer.

Three resistors, 1.1 Q. 9.0 2 and 3.2 Q, are wired in series with a power source of 7.3 volts. Calculate the potential difference in Volts across the 1.1 Q resistor. Use 2 significant figures in your answer.
