What are the 2 effects of electric current?
Answer: The two effects of electric current are; heating effect and magnetic effect.
What are its effects on current?
General effects of electric current
| Electric current (contact for 1s) | Effect |
|---|---|
| 50 to 150 mA | Extreme pain. Respiratory arrest. Muscles reactions. Possible Death. |
| 1 to 4.3 A | Fibrillation of the heart. Muscular contraction and nerve damage occur. Likely death. |
| 10 A | Cardiac arrest, severe burns. Death is probable |
What is the range of LET GO current?
9 to 30 Milliamps
Is direct current dangerous?
Direct current (DC) is more likely to cause muscle tetanus than alternating current (AC), making DC more likely to “freeze” a victim in a shock scenario. However, AC is more likely to cause a victim’s heart to fibrillate, which is a more dangerous condition for the victim after the shocking current has been halted.
Why is direct current bad?
It is much more expensive and difficult to change the voltage of direct current as opposed to alternating current, making it a poor choice for the high voltage transmission of electricity. However, for very long distances, HVDC transmission can be more efficient than alternating current.
Is TV DC or AC?
Batteries and electronic devices like TVs, computers and DVD players use DC electricity – once an AC current enters a device, it’s converted to DC. A typical battery supplies around 1.5 volts of DC.
Why do we use AC and DC current?
Electric current flows in two ways as an alternating current (AC) or direct current (DC)….A video comparing Alternating Current and Direct Current.
| Alternating Current | Direct Current |
|---|---|
| The rotating magnets cause the change in direction of electric flow. | The steady magnetism makes DC flow in a single direction. |
