Could someone please help me with these physics questions?

1. Use Kirchhoff's Laws to verify the equivalent resistance of resistors in series (Figure 10) is Rseries = R1 + R2 + R3... Record your answer in variable form. R. Battery R2 Figure 10: Two resistors in a series configuration. 2. Use Kirchhoff's Laws to verify the equivalent resistance of resistors in parallel (Figure 11) is the sum of inverse of the individual resistances. Record your answer in variable form. Battery Rparalel = + + Figure 11: Two resistors in a parallel configuration. 3. Use Kirchhoff's Law to prove that the currents going through the resistors (Figure 12) are: V, - (V2 - V1) R2 V2 - (VI - V2) R2 V1 + V. R 12 = R1 + 2 R R1 + 2 RX R1 + 2R where /, is the current through R, on the left loop, /2 is the current through R, on the right loop, /3 is the current through the middle resistor.
