yes
a circuit with no resistance or zero resistance can be considered as open circuit in which the current is zero. without resistance the circuit just becomes open ()
In a circuit , current is inversely proportional to the resistance.
The current in a short circuit may be very high because the resistance in the short circuit is probably less than the resistance in the original circuit.
V = IR Where, V = voltage I = current R = resistance Thus if resistance is increased with constant voltage current will decrease
by adding the the resistances in series the total resistance of the circuit increses and thus the crunt flowing in the circuit decrese. Ans 2 . the current in series circuit of constant resistance will always be the same . It will not effect the current .
Voltage across a resistance = (resistance) x (current through the resistance) =4 x 1.4 = 5.6If the ' 1.4 ' is Amperes of current, then the required voltage is 5.6 volts.
In an electrical circuit, the relationship between voltage and resistance is described by Ohm's Law. This law states that the voltage across a circuit is directly proportional to the resistance in the circuit. In other words, as resistance increases, the voltage required to maintain the same current also increases. Conversely, if resistance decreases, the voltage required to maintain the same current decreases.
Voltage = (current) x (resistance) Current = (voltage)/(resistance) Resistance = (voltage)/(current)
Voltage provides the "pressure" to push current "flow" through the circuit resistance.
When you add resistance to a circuit, current goes down. Ohm's Law: current = voltage divided by resistance.
"Volts" is electrical pressure applied to a circuit; whereas, "ohms" is electrical resistance to that pressure. One cannot determine ohms from voltage without knowing either the current (in "amps") or power (in "watts"). A normal 120V household circuit can handle a maximum of 20 amps, so using ohm's law of resistance = voltage / current, the minimum resistance required in a 120V household circuit would be 6 ohms. Any less than 6 ohms will cause the circuit breaker to trip.
If you add another resistor or just increase the resistance the current will decrease. I think the statement you are talking about means that whatever the current is in the series circuit it will be the same everywhere in that circuit, on both sides of the resistance. The resistance lowers the current in the entire circuit, not just after the resistance.
At constant temp.& pressure,on the same circuit,with potential difference unchanged,current reduces if resistance increases.(Ohm's law).
When you increase the resistance in a circuit, the current (amps) in the circuit will decrease. This is because Ohm's Law states that current is inversely proportional to resistance, so as resistance increases, current decreases.
A multimeter is commonly used to measure electrical pressure in a circuit. It can measure voltage, current, and resistance, providing a comprehensive view of the electrical characteristics in the circuit.
Voltage = (current) x (resistance) Current = (voltage)/(resistance) Resistance = (voltage)/(current)
Voltage = (current) x (resistance) Current = (voltage)/(resistance) Resistance = (voltage)/(current)
