In schematic diagrams, resistor symbols are sometimes used to illustrate any general type of device in a circuit doing something useful with electrical energy. Any non-specific electrical device is generally called a load, so if you see a schematic diagram showing a resistor symbol labeled “load...
Resistors in parallel connection can be defined as, whenever two or more resistors are connected to the two same nodes then it has above one path for current flow that is commonly connected to a single voltage source. Resistors in a parallel circuit, the current flows through above one path ...
Draw a circuit with resistors in parallel and in series. Calculate the voltage drop of a current across a resistor using Ohm’s law. Contrast the way total resistance is calculated for resistors in series and in parallel. Explain why total resistance of a parallel circuit is less than the sm...
However, when the switch is open, it has no direct connection to either GND or VDD(a logic HIGH); therefore, it is in a floating state and noise can make it randomly HIGH or LOW. This would be horrible for our circuit, because it would give false readings. ...
In Circuit diagram-1, suppose that the transistor T1 is in a saturated state when there is a voltage input. Circuit Diagram-1 A pulse voltage of 0-5V is input to the base of T1. When the input voltage is 5V, set T1 Ube = 0.7V, so the base current of T1: Put the bas...
A. What is the value of the resistor R in the diagram. B. What is the equivalent resistance of the three resistors in the figure? Electrical Resistance: The electrical resistance, {eq}R {/eq}, of a conductor is defined as the rati...
Total resistance of the circuit (Rs) Potential difference across the 15 Ohms resistor (V2) Formula: Rs = R1 + R2 V2 = IR2 From the circuit diagram, the two resistors are connected in series. ∴ Total Resistance of the circuit is given by ...
What happens to the current flowing through a circuit as resistance increases? Given the diagram, would adding a 2-ohm resistor in series be equal to halving the current? A 9.0-V battery is connected to a 9.0-ohm resistor and a 27-ohm resistor. The current that flows through t...
When resistors R(1) and R(2) are connected in a parallel electric circuit, the total resistance is (1)/((1)/(R(1))+(1)/(R(2))). This fraction is equivalent to
In AC CircuitsTheschematicbelow is thatofanac circuit formed by plugging a toaster into a wall socket.The heating elementofthe toaster is essentially a thin wire of resistance R and becomes redhot when the electrical energy is dissipated in itAccording to Ohm's Law, theinstantaneousvoltage v ...
