which interval probability lies.
The potential difference accross the terminals of a cell when it is not supplying any current is called e.m.f while
The voltage accross the terminals of a cell when it is supplying current to external resistance is known as Potential Difference .
When the cell is being charged
Strategy for simplifying a resistor network
@Nilesh When resistors are connected in series, the current through each resistor is the same and
the total potential difference across all the resistors is equal to the sum of the potential differences across each resistor.
For example when resistor are connected in sereis then
after increasing by 0.5%
So If both mass and radius are increased by 0.5% then and U remains unchanged where as g will be decreased.
the body is positively charged before grounding and after that electrons flows from earth to body and body becomes neutral.
the Body is positively charged before grounding because If a body is grounded and electrons starts flowing into the body from then Earth this would mean that the charges inside the body are attracting the negative electrons from Earth as a potential difference is being developed at the two ends, the Earth and the body.
answer for this qns with soln
In the mapping ; Co - domain of this function
Your Option is correct !!
An electromagnetic wave of frequency 1x1014 hertz is propagating along z - axis. The amplitude of electric field is 4 V/m. If = 8.8 x 10-12 C2/N-m2, then average energy density of electric field will be :
35.2 x 10-10 J/m3
35.2 x 10-11 J/m3
35.2 x 10-12 J/m3
35.2 x 10-13 J/m3
