If a voltage difference of 3V causes a 1.5 current, what is the resistance in the circuit
R =U/R =3/1.5 =2 Ohm
R =U/I =3/1.5 =2 Ohm
To find the resistance in the circuit, you can use Ohm's Law. Ohm's Law states that the current (I) flowing through a conductor is directly proportional to the voltage (V) across the conductor and inversely proportional to the resistance (R) of the conductor.
Mathematically, Ohm's Law is expressed as:
V = I * R
Where:
V is the voltage (3V),
I is the current (1.5A),
R is the resistance (unknown).
Rearranging the equation, we can solve for the resistance (R):
R = V / I
Substituting the given values:
R = 3V / 1.5A
R = 2 ohms
Therefore, the resistance in the circuit is 2 ohms.
To find the resistance in the circuit, we can use Ohm's Law, which states that the current (I) flowing through a circuit is directly proportional to the voltage (V) across the circuit and inversely proportional to the resistance (R) in the circuit.
Ohm's Law can be mathematically represented as:
V = I * R
where:
V is the voltage (in volts),
I is the current (in amperes), and
R is the resistance (in ohms).
In this case, we know that the voltage difference (V) is 3V and the current (I) is 1.5A.
Plugging these values into Ohm's Law equation:
3V = 1.5A * R
Now, solve for R:
R = 3V / 1.5A
R = 2 ohms
Therefore, the resistance in the circuit is 2 ohms.
