Question
**Three resistors in parallel:**

\( R_{\text{Total}} = \frac{1}{\frac{1}{R_1} + \frac{1}{R_2} + \frac{1}{R_3}} \)

---

1) **The circuit in figure (1) has**, \( V_{\text{supply}} = 40 \) Volts, \( R_1 = 30 \, \Omega \) and \( R_2 = 60 \, \Omega \).

   a) Calculate the total resistance for this parallel circuit.

   \[ R_{\text{Total}} = \_\_\_\_\_\_\_\_\_\_\_ \]

   b) Calculate \( I_1 \) and \( I_2 \), and verify if \( I_{\text{Total}} = I_1 + I_2 = \_\_\_\_\_\_\_\_\_\_\_ \)

   c) Calculate the total current for this circuit.

   \[ I_{\text{Total}} = \_\_\_\_\_\_\_\_\_\_\_ \]

**Figure (1) Explanation:**

The diagram shows a circuit with a voltage supply (\( V_{\text{supply}} \)) connected to two resistors, \( R_1 \) and \( R_2 \), arranged in parallel.
