A wattmeter is rated at 10 A and 25 V. The current coil has a resistance of 0.06 Ω and reactance of 0.02 Ω. The potential coil circuit may be assumed to be purely resistive having a resistance of 6250 Ω. The load is 10 A at a power factor of 0.174 lagging. The voltage across the load is 25 V. The percentage error due to the two different connections is __________ (up to 2 decimal places)
