Ms. Juilee,
I have some doubt,
For finding I means, I=v/R.
But why your using this formula here IR*v.
Can you explain?

Internal resistance is given by Sensivity (20,000) * scale deflection (5)
Which is 20,000 * 5 = 100,000 ohms
Which is 20,000 * 5 = 100,000 ohms

The internal resistant 20000 for 1 volt that = v = 5 and ohm law,
R = v*I 5*20000 = 100,000 ohm.
R = v*I 5*20000 = 100,000 ohm.

According to me....
Internal resistance =20000ohm/v
voltage=5v
I.R.*V=20000*5
=100,000ohm
Internal resistance =20000ohm/v
voltage=5v
I.R.*V=20000*5
=100,000ohm

In 1volt resistance is 20000 Ω.
in 5volt =5 * 20000 = 100000 Ω.
in 5volt =5 * 20000 = 100000 Ω.

Given,
r = 20,000 ohms per volt.
For 1v r = 20,000.
For 5v R = 20,000*5 = 100,000.
r = 20,000 ohms per volt.
For 1v r = 20,000.
For 5v R = 20,000*5 = 100,000.

According to ohm's law,
IR = 20,000ohm/volt.
V = 5v.
IR*V = 20,000*5 = 100000.
IR = 20,000ohm/volt.
V = 5v.
IR*V = 20,000*5 = 100000.

IR means Internal Resistance not current and resistance.
