Due to a weak connection, there is a break in the circuit (shown below) between points a and b. If R₁ = 5.132, R₂ = 2.19 02, and R3 = 15.72, and the two batteries &₁ and ₂ have voltages of 28.0 V and 6.50 V respectively, find the potential difference Vab. Be sure to include the sign of the potential difference. Vab = Vb - V₂ = V &₁ R₁ www www R₂ E₂
