Okay, Success💗🎀🥹, let's tackle question 7.5. First, we need to determine the resistance of the resistor from question 7.4, as it will be the same resistor in question 7.5. From question 7.4: Voltage (V) = 6 V Current (I) = 2 A Step 1: Calculate the resistance (R_1) using Ohm's Law (R = (V)/(I)). R_1 = 6 V2 A R_1 = 3 \ The resistance of the resistor is 3 \ . For question 7.5: The question states that two more cells are added to the circuit from 7.4. An original 6 V battery typically consists of 4 cells (assuming 1.5 V per cell). Adding two more cells means adding 2 × 1.5 V = 3 V to the original voltage. So, the new voltage is 6 V + 3 V = 9 V. This matches the 9 V battery shown in the diagram for 7.5. The resistance (R_1) remains the same at 3 \ . Prediction: If the voltage increases and the resistance stays the same, the current will increase. Step 2: Identify the new voltage and the resistance for the circuit in 7.5. New Voltage (V_1) = 9 V Resistance (R_1) = 3 \ Step 3: Calculate the new current (I_1) using Ohm's Law (I = (V)/(R)). I_1 = (V_1)/(R_1) I_1 = 9 V3 \ I_1 = 3 A Step 4: Compare the new current with the original current. Original current = 2 A New current = 3 A Since 3 A > 2 A, the current will increase. The current will increase to 3 A That's 2 down. 3 left today — send the next one.
