In the wheatstone bridge network, ABCD is balanced
where P = 100 ohm, Q = 1000 ohm and S = 130
ohms.
Determine the value of R.
Answers
Explanation:
Assuming that the wheatstone bridge network is balanced,
P/Q=R/S
here,
p=100ohm
q=1000ohm
r=?
s=130ohm
so, p/q=r/s
100/1000=r/130
1000r=13000
r=13000/1000
r= 13 ohms.
Answer:
The correct answer is 13ohm
Explanation:
Assuming that the wheatstone bridge network is balanced,
P/Q=R/S
here,
p=100ohm
q=1000ohm
r=?
s=130ohm
so, p/q=r/s
100/1000=r/130
1000r=13000
r=13000/1000
r= 13 ohms.
Resistance is the competition that a substance offers to the glide of electric current. it's miles represented by means of the uppercase letter R. the usual unit of resistance is the ohm, occasionally written out as a phrase, and on occasion symbolized through the uppercase Greek letter omega
while an electric powered current of 1 ampere passes via a aspect across which a potential difference (voltage) of 1 volt exists, then the resistance of that factor is one ohm. (For extra discussion of the relationship among modern-day, resistance and voltage, see Ohm's law.)
In standard, when the applied voltage is held constant, the cutting-edge in an immediate-current (DC) electric circuit is inversely proportional to the resistance. If the resistance is doubled, the present day is cut in 1/2; if the resistance is halved, the modern is doubled. This rule also holds actual for most low-frequency alternating-modern-day (AC) structures, which includes household application circuits. In some AC circuits, mainly at high frequencies, the state of affairs is extra complex due to the fact a few components in these systems can keep and launch energy, in addition to dissipating or changing it.
the electric resistance in step with unit length, vicinity, or volume of a substance is referred to as resistivity. Resistivity figures are often distinct for copper and aluminum twine, in ohms consistent with kilometer.
