2. You should measure DC power dissipated in a resistive load indirectly using a DC voltmeter and ammeter. You connected a voltmeter in parallel with the load and an ammeter in series with the load. The voltmeter reading is 10 V, but ammeter reading is 1 A. Voltage measurement uncertainty is 0.4 V, but current measurement uncertainty is 10.08 A. Estimate measurement uncertainty of power (AP) assuming that random error dominates.
