How do you calculate current from voltage and resistance?
From this, we conclude that; Current equals Voltage divided by Resistance (I=V/R), Resistance equals Voltage divided by Current (R=V/I), and Voltage equals Current times Resistance (V=IR). The important factor here is the temperature.
What is the resistance of a circuit with voltage 40 V and current 8 A?
R=408 = 5 Ω
How do you calculate current?
The current is the ratio of the potential difference and the resistance. It is represented as (I). The current formula is given as I = V/R. The SI unit of current is Ampere (Amp).
What is current divided by voltage?
One way Ohm’s Law can be stated is: “a current flowing through a conductor is directly proportional to the voltage, given the temperature of the conductor remains constant”. Putting these into words Ohm’s Law states that: Voltage equals resistance multiplied by current. Resistance equals voltage divided by current.
What is the current when the resistance is 5 ohms?
Explanation: 10/5= 2 Current =2 amperes.
What can you infer about the relationship between current and resistance?
The relationship between current, voltage and resistance is expressed by Ohm’s Law. This states that the current flowing in a circuit is directly proportional to the applied voltage and inversely proportional to the resistance of the circuit, provided the temperature remains constant.
What is the relationship between current I and voltage V?
The current I in amps (A) is equal to the power P in watts (W) divided by the voltage V in volts (V): The current I in amps (A) is equal to the square root of the power P in watts (W) divided by the resistance R in ohms (Ω): The voltage V in volts (V) is equal to the current I in amps (A) times the resistance R in ohms (Ω):
What is the formula to convert voltage to resistance?
Formula to convert volts to resistance (Ohm Law): 1 R = Resistance in Ohm. 2 I = Current in Amperes. 3 V = Voltage. To convert from volts to resistance, only the voltage between the current must be divided with the formula of the law of ohm.
What is the relation between resistance and current in amps?
The resistance R in ohms (Ω) is equal to the power P in watts (W) divided by the squared current I in amps (A): The current I in amps (A) is equal to the voltage V in volts (V) divided by the resistance R in ohms (Ω): The current I in amps (A) is equal to the power P in watts (W) divided by the voltage V in volts (V):
