d) Draw a schematic diagram of an electric circuit consisting of a battery of two
cells each of 1.5 V,512, 101 and 151 resistors and a plug key, all connected in
series
Answers
Answer:
a. We can say that the resistance of a wire is 1 ohm when 1 Ampere of current passes through the wire having a potential difference of 1 volt across it's ends.
1 Ω = 1 V/1 A
b. so if length get halfed then resistance will also get halved.
c.R total = R1 + R2
R total = 2 + 2 = 4 ohm
d.Given: an electric circuit consisting of a battery of two cells of 1.5 V each, three resistance of 5 ohm, 10 ohm and 15 ohm respectively and a plug key all connected in series.
To draw the schematic diagram of the electric circuit
Solution:
The above figure shows the required schematic diagram,
Here I have written 3V instead of 1.5V asit it given there is a battery of two cells of 1.5 V each, i.e., 1.5×2=3V
