A 5 ohm resistor a 20 ohm resistor and a 25 ohm resistor are all connected in series to a 100 volt power source What is the current running through the circuit?
To find the current running through the circuit, you need to use Ohm's Law, which states that the current flowing through a conductor between two points is directly proportional to the voltage across the two points, and inversely proportional to the resistance between them. You can use the following formula to calculate the current: I = V / R Where I is the current, V is the voltage, and R is the resistance. In this case, the total resistance of the circuit is the sum of the individual resistances, which is 5 ohms + 20 ohms + 25 ohms = 50 ohms. Therefore, the current flowing through the circuit is: I = 100 volts / 50 ohms = 2 amps.

Using schering bridge how you find capacitance?
A Schering Bridge is a bridge circuit used for measuring an unknown electrical capacitance and its dissipation factor. The dissipation factor of a capacitor is the the ratio of its resistance to its capacitive reactance. The Schering Bridge is basically a four-arm alternating-current (AC) bridge circuit whose measurement depends on balancing the loads on its arms. Figure 1 below shows a diagram of the Schering Bridge.In the Schering Bridge above, the resistance values of resistors R1 and R2 are known, while the resistance value of resistor R3 is unknown. The capacitance values of C1 and C2 are also known, while the capacitance of C3 is the value being measured. To measure R3 and C3, the values of C2 and R2 are fixed, while the values of R1 and C1 are adjusted until the current through the ammeter between points A and B becomes zero. This happens when the voltages at points A and B are equal, in which case the bridge is said to be 'balanced'.When the bridge is balanced, Z1/C2 = R2/Z3, where Z1 is the impedance of R1 in parallel with C1 and Z3 is the impedance of R3 in series with C3. In an AC circuit that has a capacitor, the capacitor contributes a capacitive reactance to the impedance. The capacitive reactance of a capacitor C is 1/2πfC.As such, Z1 = R1/[2πfC1((1/2πfC1) + R1)] = R1/(1 + 2πfC1R1) while Z3 = 1/2πfC3 + R3. Thus, when the bridge is balanced:2πfC2R1/(1+2πfC1R1) = R2/(1/2πfC3 + R3); or2πfC2(1/2πfC3 + R3) = (R2/R1)(1+2πfC1R1); orC2/C3 + 2πfC2R3 = R2/R1 + 2πfC1R2.When the bridge is balanced, the negative and positive reactive components are equal and cancel out, so2πfC2R3 = 2πfC1R2 orR3 = C1R2 / C2Similarly, when the bridge is balanced, the purely resistive components are equal, soC2/C3 = R2/R1 orC3 = R1C2 / R2.Note that the balancing of a Schering Bridge is independent of frequency.
Does adding resistors in series increase or decrease the overall resistance of a circuit?
Resistance in series adds together. two 100 ohm resistors in series are equivalent to one 200 ohm resistor. to make an equation out of it ( even though it is simple) you can say: Rtotal=R1+R2+R3...+Rn
How do you design active single transistor low pass filter?
Using an appropriate transistor, set up the base bias in the normal fashion, same for the emitter resistor.You then need RC feedback emitter to base. This will take the form of a t filter: base input>c1>r1(to emitter)>c2(to base)C2 = 2×C1R1=R2×R3/(R1+R2)Fo=1.414/(4π×R1×C2)See external link for more.
What happens to the current of R1 connected in series with R2 when it is also connected in parallel with R3?
The current, if connected to a voltage source that can supply the needed current to (R1+R2) R3, will be unchanged. If the source cannot supply the needed current, the terminal voltage will decrease, which will change the current flowing through R1 and R2.
How would the hook up 3 resistors in a circuit to get a maximum current?
In series, R = R1 + R2 + R3 + ... The current in a series connection will only have 1 path. The current is the same through each resistor

How are current and voltage affected in series and parallel circuits?
Voltage is Current multiplied by Resistance. The formulas for calculating the resistance in parallel and series circuits are: Resistors in Series: R(total)=R1+R2+R3+... Resistors in Parallel: 1/(Rtotal)=(1/R1)+(1/R2)+... Current is a measure of Coulombs of charge per unit of time or I=C/t The current depends on the circuit, whether it has capacitors or resistors, and the exact layout. Current 'flows' through wires in much the same way that water flows through pipes, so if the current meets some resistance (a resistor), some of the current will go through the resistor, but the rest will go through any other available path (like in a parallel circuit).

Why do the current changes?
The amount of current that flows in a circuit is proportional to the voltage and inversely proportional to the resistance, as per Ohms law (I=V/R) where I is current.When resistances (IE loads) are connected in series, the total resistance is the sum of the loads (IE Rtotal = R1 + R2 + R3 ...)When they are connected in parallel, the total resistance is the inverse sum of the reciprocals of each resistance (IE 1/Rtotal = 1/R1 + 1/R2 + 1/R3 ...)Therefore in parallel the total resistance is much lower, and therefore at the same voltage more current will flow.
