Perhaps you're familiar with the myth that getting between the neutrals can hurt you worse than touching the hot. In fact, grounded (neutral) conductors can be as dangerous as ungrounded (hot) wires. The danger of electrocution exists any time the voltage is in excess of 30V. Consider what happens when a person becomes part of the neutral of a 120V circuit. Ohm's and Kirchoff's Law will be the basis of our calculations.
In our example, the resistance of each circuit conductor is 0.20 ohms (100 ft of 12 AWG), the load has a resistance of 200 ohms, and our accident victim has a skin contact resistance of 1,000 ohms. To determine the voltage (potential) with our accident victim as part of the neutral current path, we need only perform four short calculations:
Step 1. Determine the total resistance of the series circuit using Ohm's Law.
RT=R1+R2+R3+R4
R1=Hot Wire=0.20 ohms
R2=Load=200 ohms
R3=Person=1,000 ohms
R4=Neutral Wire=0.20 ohms
RT=0.2 ohms+200 ohms+1,000 ohms+0.2 ohms
RT=1,200.40 ohms
Step 2. Determine the current of the series circuit.
I=E÷RT
I=120V÷1,200.40 ohms
I=0.0999667A
Step 3. Determine the voltage drop across each resistor.
E=I×R
E Line=0.0999667A×0.20 ohms=0.02V
E Load=0.0999667A×200.00 ohms=20.00V
E Person=0.0999667A×1,000 ohms=99.96V
E Neutral=0.0999667A×0.20 ohms=0.02V
Step 4. Using Kirchoff's Law, verify the sum of the voltage drops of the circuit is equal to the voltage source.
ET=E1+E2+E3+E4
ET=0.02V+20V+99.96V+0.02V=120V
By applying two fundamental laws in four math steps, we have proven:

The voltage potential between the accident victim and the neutral wire is almost 100V.

The electric shock hazard (100V) from the neutral is not greater than the shock hazard from a hot and neutral (120V), but it is just as dangerous.
You must realize that it's not necessary to get between two broken neutral conductors to receive a shock. You can receive the same shock if you contact the end of the neutral at the load and any grounded surface. And remember, even a ground fault circuit interrupter (GFCI) will not protect you against electric shock from a neutraltoneutral (series) or a linetoneutral (parallel) connection.
