If internal body resistance is 100 ohms, left-hand contact resistance is 350 ohms, and foot contact resistance with the ground is 550 ohms, what is the total resistance?

To calculate the total resistance in the given scenario, you need to determine how the resistances are configured within the circuit. In this case, the internal body resistance, left-hand contact resistance, and foot contact resistance are all in series. When resistances are arranged in series, the total resistance is simply the sum of the individual resistances.

Here’s how the calculation works:

1. Internal Body Resistance: 100 ohms

2. Left-Hand Contact Resistance: 350 ohms

3. Foot Contact Resistance with the Ground: 550 ohms

You sum these three resistances together:

100 ohms (internal body) + 350 ohms (left hand) + 550 ohms (foot contact) = 1000 ohms total resistance.

This total resistance represents the effective opposition to the flow of electrical current through the entire path that current would take, combining contributions from each resistance element.

Therefore, the correct total resistance is 1000 ohms.
