Explanation
1 Volt (V) is equal to 1 Joule per Coulomb (JC^-1).
-
A. Electric field gradient
-
B. Electric power
-
C. Electric potential
-
D. Electric intensity
Explanation
The formula 𝑉 = 𝑊/ 𝑞0 represents electric potential, where 𝑉 is the potential, 𝑊 is the work done, and 𝑞0 is the test charge.
سیل کے ای ایم ایف کی پیمائش کے لیے بہترین آلہ ______ ہے؟
-
A. Ammeter
-
B. Voltmeter
-
C. Multimeter
-
D. Potentiometer
Explanation
The best instrument for measuring the EMF of a cell is a potentiometer.
It provides a precise measurement by comparing the cell’s EMF with a known reference voltage without drawing current from the cell.
