Question

**Series Resistors and Equivalent Resistance Calculation**

Three resistors, 21 Ω, 52 Ω, and 100 Ω, are connected in series, and a 0.50 A current passes through them.

**Question:**

(a) What is the equivalent resistance?

(b) What is the potential difference across this equivalent resistance?

**Answer Fields:**

(a) [ Number ] [ Units ]

(b) [ Number ] [ Units ]

**Explanation:**

When resistors are connected in series, their resistances add up to form the equivalent resistance. The formula is:

\[ R_{\text{eq}} = R_1 + R_2 + R_3 \]

For the potential difference, Ohm's law is used:

\[ V = I \times R_{\text{eq}} \]

where:
- $ V $ is the potential difference,
- $ I $ is the current (0.50 A in this case),
- $ R_{\text{eq}} $ is the equivalent resistance calculated above.

Expert Solution

Step 1

If R1,R2,R3 resistances are in series then their equivalent resistance is

R_eq = R1+R2+R3
