Problem #1 Solution

Step 1:

Combine the two parallel resistors (R2 and R3) into a single equivalent resistor by adding reciprocally.

Step 2:

Combine the three resistances in series to find the total resistance of the circuit.

Step 3:

Calculate the total circuit current using Ohm's Law.

Step 4:

Calculate the voltage drop across R1 using Ohm's Law.
