Sum the individual voltage drops.

Here's the solution for Question 1a: a) Determine the battery voltage V Step 1: Sum the individual voltage drops. In a series circuit, the total voltage supplied by the battery is the sum of the voltage drops across each resistor. V = V_1 + V_2 + V_3 Substitute the given potential differences: V = 5\,V + 2\,V + 6\,V V = 13 V b) Determine the total resistance of the circuit Step 2: Express total resistance using Ohm's Law. The total resistance R_total of a series circuit is the sum of individual resistances, or the total voltage divided by the total current I. R_total = (V)/(I) Substitute the total voltage from part (a): R_total = (13\,V)/(I) Since the current I flowing through the circuit is not provided, the exact numerical value for the total resistance cannot be determined. It is expressed in terms of I. c) Determine the values of resistance of resistors R1, R2 and R3 Step 3: Express individual resistances using Ohm's Law. For resistors in a series circuit, the current I is the same through each resistor. Using Ohm's Law (V = I · R): R_1 = (V_1)/(I) R_2 = (V_2)/(I) R_3 = (V_3)/(I) Substitute the given potential differences: R_1 = (5\,V)/(I) R_2 = (2\,V)/(I) R_3 = (6\,V)/(I) Since the current I is not provided, the exact numerical values for R_1, R_2, and R_3 cannot be determined. They are expressed in terms of I. Send me the next one 📸
