Question
Calculate the current $I$ in the circuit of Fig. 149.
Step 1
First, we need to find the total resistance in the circuit. We can see that the resistors R1 and R2 are connected in series, so their combined resistance is simply the sum of their individual resistances: R_total = R1 + R2 = 10 ohms + 20 ohms = 30 ohms. Show more…
