Final answer:
In dc electrode positive, the power at the work clamp is determined by the voltage of the battery.
Step-by-step explanation:
In dc electrode positive, the work clamp is connected to the positive terminal of the battery. Therefore, the power at the work clamp is determined by the voltage of the battery.
For example, if the battery has a voltage of 12 volts, then the power at the work clamp would be 12 watts when a current flows through the circuit.
This is because power is calculated by multiplying the voltage (V) by the current (I). So, if the current is 1 ampere (A) and the voltage is 12 volts (V), then the power would be 12 watts (W): P = V * I.
