The potential drop increases as more cells are connected in series form.
In series circuit connection, the current across the cells is the same but the voltage varies.
When a circuit is connected to a single cell, the potential drop is given as;
where;
V is the potential drop
I is the current
r is the resistance
However, when two cells are connected in a row or serially, the total voltage drop is given as;
Thus, potential drop increases as more cells are connected in series form. The electricity in our homes and factories are connected in parallel form to reduce this voltage drop.

Answer:10km/hr
Explanation:
Displacement=35-10
displacement=20km
Velocity =displacement/time
Velocity =20/2
Velocity =10km/hr
The atomic number of an element is the number of protons the element has, so the element with the atomic number 55 has 55 protons.
Answer:
F = 0.408 N
Explanation:
It is given that,
Weight of a wooden block, W = 8 N
Weight, W = mg
m is mass of wooden block
Acceleration of the block, a = 0.5 m/s²
Force, F = ma
So, the magnitude of force applied to the wooden block is 0.408 N.
Answer:
2.4 meters
Explanation:
Let
m1= 10 kg
m2= 6 kg
Distance of m2 from pivot = 4 m
Distance of m1 from pivot = x (suppose) =?
If system is not rotating then it should be in equilibrrium position. And in this case clock-wise and anti -clock wise torques should balance each other i-e
weight of m1 mass bolck × x = weight of m2 mass block × 4
m1×g× x = m2 × g × 4
==> 10×9.8×x= 6×9.8×4
==> x = 6×9.8×4 / 10×9.8
==> x = 24/10=2.4 m
