Answer:
Explanation:
Let the four resistances of th wheat stone bridge is
P, Q, R and S and the value of each is 350 ohm.
Here, P and Q are in series.
R' = P + Q = 350 + 350 = 700 ohm
Then R and S are in series
R' = R + S = 350 + 350 = 700 ohm
Now R' and R'' are in parallel.
So, the equivalent resistance is
Req = R' x R'' / ( R' + R'')
Req = 700 / 2 = 350 ohm
Thus, the reading of ohmmeter is 350 ohm.
A positive charge and a negative charge held a certain distance apart are released. as they move, the force on each particle increases
The most common charge carriers are the positively charged proton and the negatively charged electron. The movement of any of these charged particles constitutes an electric current
<h3>What is a Charge ?</h3>
When there are more or fewer protons in an atom than electrons, the substance has an electric charge. Protons have a positive charge, while electrons have a negative charge. If a substance has more protons than electrons, it is positively charged; if it has more electrons, it is negatively charged.
- The SI units for charge are ampere-second or coulomb. When one ampere of electric current goes through the conductor for one second, one coulomb of charge passes through it. Charge is denoted by the formula Q = I t.

It slows the object down so it cannot move well and evetually the object cannot be pushed and farther
