Answer:
Same
Explanation:
Let R be the resistance of the cell and E be the emf.
Let i be the current in the circuit.
i = E / R ..... (1)
Now emf and resistance be doubled.
so, i' = 2E/2R = E/R
So, i' = i (From equation (1)
Current remains same.
Answer:
magnitude
Explanation:
The Richter scale compares the magnitude or energy of earthquakes
