ohm resistor and an 18.0 ohm resistor are connected in parallel across a 15.0 Vb

Question

ohm resistor and an 18.0 ohm resistor are connected in parallel across a 15.0 Vbattery. Analyze the circuit to determine the values describedbelow. (Hint, you do not necessarily need to complete the parts inthe order listed.) a) What is the equivalent resistance across the combination of thetwo resistors? ohm b) What is the current out of the battery? A c) What is the voltage out of the battery? V d)What is the voltage drop across the 40.0 ohm resistor? V e) What is the voltage drop across the 18.0 ohm resistor V f) What is the current through the 40.0 ohm resistor? A g) What is the current through the 18.0 ohm resistor? A

Explanation / Answer

A.) For resistors in parallel, 1/40 + 1/18 = 12.4 B.) I = V/R = 15V/12.4 = 1.21A C.) V = 15V D.) and E.) In a parallel circuit, the voltagedrop across each resistor is the same and is the voltage suppliedby the battery. F.) I = V/R = 15V/40 = 0.375A G.) I = V/R = 15V/18 = 0.833A Hope that helps
