What do you mesure the answer of Ohm's law in?
Ohm's law can be used to find the current, voltage or resistance in a electrical circuit. The formula is V=IR where 'V' is the Voltage measured in Volts (V), 'I' is the current measured in Amperes (A) And 'R' is the resistance, measured in Ohms (Ω)
What are Ohms Law and the Power Law?
Ohms Law is used for the measurement of resistance. You can find the resistance in a series circuit using this equation; amps=volts/resistance or volts=amps x resistance.The Power Law is used to find the wattage in the circuit. You can find the amount of watts using this equation: watts=volts x amps.CommentOhm's Law has nothing whatsoever to do with either resistance or power.The equation, R = E/I, is derived from the definition of the ohm, and not from Ohm's Law.Ohm's Law simply describes a linear relationship between the potential difference across a conductor and the current through it. It does NOT describe the relationship between potential difference, current, and resistance.
What is common to both thevenin and norton theorem?
To solve any D.C. circuit by using Thevenin Theorem,First of all load resistance RL is disconnected from the circuit and open circuit voltage across the circuit is calculated (known as Thevenin equivalent voltage)Secondly, the battery is removed by leaving behind its internal resistance. Now we calculate equivqlent resistance of the circuit ( called Thevenin equivalent resistance).Now we connect Thevenin Voltage in series with Equivalent resistance of the circuit and now connect load resistance across this circuit to calculate current flowing through the load resistance.Whereas in the case of using Norton theorem, we again remove the load resistance if any, and then short circuit these open terminals and calculate short circuit current Isc.Second step is same as in Thevenin theorem i.e. remove all sources of emf by replacing their internal resistances and calculate equivqalent resistance of the circuit.Lastly, join short circuit current source in parallel with equivalent resistance of the circuit. Now, we can calculate votage across the resistance which was connected in parallel with Isc.So, by knowing the open circuit voltage, we can calculate current flowing the resistance and on the other hand , by knowing the short curcuit current , we can calculate voltage across the resistance.
If the current went through a circuit is 0.0030 A. What is the resistance of this circuit if the voltage difference across the circuit is 12 V?
To find the resistance of the circuit, you can use Ohm's Law, which states that ( R = \frac{V}{I} ), where ( R ) is resistance, ( V ) is voltage, and ( I ) is current. Given that the current ( I ) is 0.0030 A and the voltage ( V ) is 12 V, the resistance ( R ) can be calculated as follows: [ R = \frac{12 , \text{V}}{0.0030 , \text{A}} = 4000 , \Omega. ] Thus, the resistance of the circuit is 4000 ohms (or 4 kΩ).
How do you find the missing Resistor in a series?
To find the missing resistor in a series circuit, first calculate the total resistance using the formula ( R_{total} = R_1 + R_2 + R_3 + ... + R_n ), where ( R_1, R_2, R_3, ) etc., are the known resistors. Rearrange the equation to solve for the missing resistor ( R_x ) as ( R_x = R_{total} - (R_1 + R_2 + ... + R_n) ). If you know the total voltage and current in the series, you can also use Ohm’s Law (( V = I \times R )) to find the total resistance and then determine the missing resistor.
How do you find resistance in a circuit?
That entirely depends on whether the resistances are in series or in parallel with each other. Ohm's law states that I=V/R. i.e. current = voltage/resistance. If you know the current and voltage you can find the resistance. You can use algebra to rearrange the formula for R and get that R= V/I. Resistance = voltage/current.
What is the current in a circuit that has a resistance of 30 ohms and a power of 2 watts?
To find the current in the circuit, you can use the formula: Power = Current^2 * Resistance. Given the values, you can rearrange the formula to solve for current: Current = sqrt(Power / Resistance). Plugging in the values, you get Current = sqrt(2 / 30) which simplifies to approximately 0.27 amperes.
How to calculate the current in a circuit?
To calculate the current in a circuit, you can use Ohm's Law, which states that current (I) equals voltage (V) divided by resistance (R). The formula is I V/R. Simply plug in the values for voltage and resistance to find the current flowing through the circuit.
What is the formula to find out the total resistace of the series parellel circuit?
i think first one should find out the series resistance that is R1+R2+R3 and after that parellel resistance that is 1/R1+1/R2+1/R3 and after that add the series resistance and parellel resistance to get the total resistance
How do you find out the resistance on a circuit?
E = I* R is Ohm's Law. Where: E = voltage I = current R = resistance Using simple algebra yields: R = E / I
What is meant by calculate the equivalent resistance of the circuit from the measured potential difference across the battery and the current through the battery is there a formula for this?
In a complex circuit with various elements (resistors, capacitors etc.) and one battery, the various circut elements contribute to draw a certain amount of current "I"from the battery at some terminal voltage "V". The "equivalent" resistance of the various circuit elements is that resistance "R" which will draw the same current , at the same terminal voltage, as the complex circuit. So to find "R" you simply imagine replacing the complex circuit with "R" by attaching "R" across the terminals of the battery and use Ohms law to find "R" , demanding "I" and "V" are the same. So then R = V/I.
How do you find resistance when you have current and resistance total?
If you are looking for the resistance of each resistor in either a series circuit or a parallel circuit you must measure the current I and the voltage V for each resistor. Then calculate its resistance using Ohms Law R = V / I where I = current (Amps), V = voltage (Volts) and R= resistance (Ohms).
What is the net resistance of the circuit connected to the battery in the figure?
To find the net resistance of the circuit connected to the battery in the figure, you need to calculate the total resistance by adding up the individual resistances in the circuit.
What is the formula to find the current of something?
The formula to find the current (I) of an electrical circuit is given by Ohm's Law, which states that current equals voltage (V) divided by resistance (R). Mathematically, it is expressed as ( I = \frac{V}{R} ). Here, current is measured in amperes (A), voltage in volts (V), and resistance in ohms (Ω).
When using a 60.0 W light bulb in a household circuit what is the resistance?
To calculate the resistance of the 60.0 W light bulb, you need to know the voltage of the household circuit. Using the formula P = V^2 / R (where P is power in watts, V is voltage in volts, and R is resistance in ohms), you can rearrange to solve for resistance: R = V^2 / P. Substitute the given power (60.0 W) and the voltage of your household circuit to find the resistance.
How do you calculate inductive resistance in a parallel circuit when your known is 150vr?
To calculate inductive resistance (also known as inductive reactance) in a parallel circuit, you first need to determine the frequency (f) of the alternating current (AC) supply and the inductance (L) of the inductor in henries. The inductive reactance (X_L) is calculated using the formula (X_L = 2\pi f L). Once you have X_L, you can use it in conjunction with the voltage (150 V) to find the current through the inductor using Ohm's Law: (I = \frac{V}{X_L}). If you need the total impedance or equivalent resistance in the parallel circuit, you would also need to consider the other branches of the circuit.
What is the equivalent resistance through the entire circuit?
The equivalent resistance is the overall effect all of the resistances in a circuit has. Put another way, it is the value a single resistor in a circuit would have to be in order to have the same effect as all of the resistors resistors combined in a given circuit.
