What is the current through a 4 and 8 ohm resister in sereis with 12 volts across both resisters?

Total resistance (thevinen resistance) = 4 + 8 Total voltage = 12 volts. Ohms law: I = V / R Therefore I = 12/12 = 1 amp.


How do you increase the amps in your stun gun?

Increasing the amps in a stun gun involves modifying the circuitry to allow more current to flow through the device. This can be achieved by adjusting the resistance in the circuit or by using a higher voltage power source. However, it is crucial to note that increasing the amperage in a stun gun can make it more dangerous and potentially lethal, as amperage is a key factor in determining the severity of electric shock. It is not recommended to modify stun guns in this manner, as it can pose serious risks to both the user and the target.


Two resisters have the same resistance but different cross sectional area what is difference?

If two resistors of have same value but different in shape or cross sectional area, as you said so. Then the difference may be the length of the other resistor. In short, one resistors cross sectional area is wide and other is lenghty.


If you have two 75 ohm resisters one 150 ohm resistor and one 300 ohm resistor in a series circuit which one will cause the largest voltage drop?

Ohms law is: V = I x R (voltage = current x resistance) ... therefore the larger the resistance the larger the voltage drop across that resistance.


How is a resistor different from a fuse?

A resistor is a material that attenuates the current through a conductor. An insulator isolates the conductor from the surrounding material.
