Calculate the current
through the galvanometer when a potential difference of 10 V is maintained
across AC as shown in the image.
SOLUTION:
KIRCHHOFF'S SECOND LAW:
Kirchhoff's subsequent(second) law is otherwise called Voltage law (OR) Loop law.This law depends on LAW OF CONSERVATION OF ENERGY.Kirchhoff's subsequent law expresses that " THE ALGEBRAIC SUM OF ALL THE POTENTIAL DIFFERENCES ALONG A CLOSED LOOP IS ZERO".
CONVENTIONS:
Accept any course (direction) as the heading of traversal (direction of traversal). (Either clockwise or anticlockwise)
EMF of the cell is POSITIVE in the event that the bearing of the crossing (direction of the traversal) is from its NEGATIVE terminal to POSITIVE terminal. (NPP)
EMF of the cell is NEGATIVE assuming the heading of the crossing (direction of the traversal) is from its POSITIVE terminal to NEGATIVE terminal of the battery. (PNN)
The IR item is taken as POSITIVE on the off chance that the resistor is crossed a similar way as the expected to be current. (If the resistor is traversed in the same direction as the assumed current.)
TORQUE: Torque is a winding power (twisting force) follows up on an article that produces revolution of an item and is given by the cross result ( product ) of position vector and the force vector. DIFFERENCES BETWEEN HORSEPOWER AND TORQUE: HORSE POWER: Power is the numerical item. Power is determined from torque and RPM Pull (Horsepowe r) is the proportion of motor's general performance across all conditions. Pull (Horsepower) resembles the volume of a sound system. Pull (Horsepower ) and force (torque) are set by the designers renting execution against superb eco-friendliness. Pull (Horsepower) and torque are identified with each other. TORQUE : Torque is estimation of contorting power and is a part of pull. The measure of force (torque) that motor can apply relies upon motor's RPM . Torque is the estimation of the most extreme winding power when it is going about its hardest responsibilities. Torque resembles the bass attribut...
