Current causes harm by its heating effects. The flow of electrons heats the conductor - which might be your body - and if it heats it enough the molecules break down and you are cooked.
Voltage is harmless. Static electricity generated by (for example) rubbing your shoes on a carpet can amount to thousands of volts, but does no harm.
Do not touch electrical conductors regardless of their voltage - they are harmful.
What else can I help you with?
What will cause an increase in current flow in a simple series circuit?
An increase in voltage or a decrease in resistance will cause an increase in current flow in a simple series circuit. This is because current is directly proportional to voltage and inversely proportional to resistance according to Ohm's Law.
Does voltage divided by watts equal the current?
Electric power is not defined as current divided by voltage. Electric power (Watts) is equal to amps times voltage
How do i fine an expression for power that involves only current and voltage?
You do not need ohm's law to relate power to current and voltage. Power is current times voltage. If you know current and voltage, you do not need to know resistance.
What does 5 ampere does to a human?
A 5 ampere current passing through a human body can potentially cause cardiac arrest or severe burns, depending on the path the current takes. It is important to avoid exposure to currents above safe limits to prevent serious injury or death.
Will circuit breaker cause voltage drop in outlet?
A breaker is a current activated device. New to these forums so, not sure on the etiquette of improving the answer above. I didn't see a button to provide a second answer. That being said; While the breaker reacts to current and not Voltage, Voltage drop to a motor load will cause that motor to draw more current, which can trip the breaker. The higher current draw will also create more Voltage drop, etc. Your best bet is just to stay within the industry standard of 3% drop for feeders, 5% for branch circuits. If this question doesn't involve motors, then Voltage drop outside tolerance will eventually cause the device to malfunction, depending on the severity of the drop, but won't effect the circuit breaker.
What is the lowest value of current that may cause death?
It is difficult to define the value which may cause death. I think it the voltage which is dangerous. Approximately a voltage of 50V is dangerous for heart.
How does voltage cause current to do work?
A voltage will cause electrons or other charge carriers to flow (if there is a path through which they can flow). In other words, it will cause a current.
Will the source voltage lead or lag the current in a circuit?
In an AC circuit, the source voltage can either lead or lag the current, depending on the type of load. Inductive loads cause the voltage to lag the current, while capacitive loads cause the voltage to lead the current.
Which parameter causes death due to electric shock either the voltage or the current?
This is usually specified in terms of the current. But the current is caused by a voltage.
What forces cause current to move?
Voltage
What is applied to a conductor to cause current flow?
voltage is applied to a conductor to cause a current flow
How do we usually think of voltage as the cause and currents the effect?
You apply a voltage across a load and the result is that a current flows through the load. So you must have the voltage present, the cause, before current flow, the effect. Think of voltage as pressure and current as flow.
How does voltage cause current to work?
Voltage provides the "pressure" to push current "flow" through the circuit resistance.
What cause the voltage t lead current in an ac circuit?
Voltage leads current or, more specifically current lags voltage, in an inductive circuit. This is because an inductor resists a change in current.
What is meant by lead and lag?
The terms, 'lagging' and 'leading', describe the relationship between a circuit's load current and supply voltage. They describe whether the load current waveform is leading or lagging the supply voltage -always the current, never the voltage. Inductive loads always cause the current to lag the supply voltage, whereas capacitive loads always cause the current to lead the supply voltage.
What is meant by lagging and leading circuit?
The terms, 'lagging' and 'leading', describe the relationship between a circuit's load current and supply voltage.

Inductive loads always cause the current to lag the supply voltage, whereas capacitive loads always cause the current to lead the supply voltage.
Can a short circuit cause low voltage?
Most likely a short circuit will cause no voltage. Due to the high current on a short circuit fault the over current protection of the circuit will trip. This will cut the voltage supply off completely.
