The figure below shows an AC source, a transformer with a turns ratio of N₁/N₂ = 2.40, a source resistor R, and a load resistor R₁. R₂ ww ΔV, eeeee N2₂ Ω R₁ A voltmeter across the load resistor measures an rms voltage of 24.0 V when the load resistor R₁ is 58.0 and the rms source voltage is AVS = 84.0 V. (a) Determine the value of the source resistor R, (in Q2). Ω (b) What If? If the turns ratio is increased to 3.00, determine the source resistance (in ) required to deliver the same amount of power to the load.
