I need to draw a circuit diagram to show this but I have no idea how do you find the resistance of a lamp in a circuit?
If you have a lamp, you can assume that the resistance of the lamp when it is under power will follow the ohms law.
BUT, one thing you must remember is, when a lamp is under load, it is glowing HOT. When metal is HOT, the molculoes of the meals are in much more active state. When this happens, the resistance will increase. Conversely, when the lamp is NOT on ON state, the filaments are cold. Moleculoes in the filaments are not as active. Thus, the resistance is lower. There is almost 10 to 1 difference in resistance from hot to cold.
Taking out a multimeter and measuring the resistance of the lamp will not help you determine the resistance of the lamp when it is actually under load (with voltage applied) Really, the only thing you can do is to measure the voltage, measure the current, then arrive at the resistance mathmatically.
What else can I help you with?
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 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 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 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.
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.
How do you calculate thevenis resistance in thevenis ckt?
First,remove all current and voltage sources ie replace voltage source with a short and keep current source open.Now draw the equivalent resistance-only circuit and find the equivalent resistance as viewed from the terminals of the circuit.

What is the wheat stone bridge principle?
It is an circuit that is used to find the value of the resistances. The main principle behind it is the balancing an circuit by means of varying an resistance on connected to an arm of the circuit.When the resistance become equal to the variable resistance no current flows thus we can find the value of the resistance.
Using ohm's law what is the formula to find the resistance in a circuit?
Resistance of the circuit = (voltage across the circuit) divided by (current through the circuit)
