Three resistors are connected as shown below. R1 = 25 Ω, R2 = 35 Ω, and R3 = 28 Ω. The voltage across the battery is 90 V. What is the current through R3, in Amperes? Your answer needs to have 2 significant figures, including the negative sign in your answer if needed. Do not include the positive sign if the answer is positive. No unit is needed in your answer, it is already given in the question statement.
