**Parallel Circuit with Three Lamps**In the circuit below, there are three lamps connected in parallel:- **Diagram Description**: The diagram shows a battery with a voltage \( V \), labeled as 120 Volts. Three lamps, labeled as L1, L2, and L3, are connected in parallel to the battery.**Lamp Specifications:**- The voltage of the battery is 120 Volts.- Each lamp has a nominal voltage of 120 volts, but they have different power ratings: - \( P(L1) = 600 \, \text{W} \) - \( P(L2) = 1200 \, \text{W} \) - \( P(L3) = 300 \, \text{W} \)**Task:**Calculate the current drawn from the battery.**Solution:**To find the total current supplied by the battery, we use the formula for power \( P = V \times I \), where \( P \) is power, \( V \) is voltage, and \( I \) is current. Rearranging gives \( I = \frac{P}{V} \).- For L1: \( I(L1) = \frac{600 \, \text{W}}{120 \, \text{V}} = 5 \, \text{A} \)- For L2: \( I(L2) = \frac{1200 \, \text{W}}{120 \, \text{V}} = 10 \, \text{A} \)- For L3: \( I(L3) = \frac{300 \, \text{W}}{120 \, \text{V}} = 2.5 \, \text{A} \)**Total Current**:The total current drawn from the battery is the sum of the currents through each lamp:\[ I_{\text{total}} = I(L1) + I(L2) + I(L3) = 5 \, \text{A} + 10 \, \text{A} + 2.5 \, \text{A} = 17.5 \, \text{A} \]
