In the circuit, the battery is ideal. A voltmeter of infinite resistance is connected in turn across R1 and R2, giving reading of V1 and V2 respectively. giving reading of V1 and V2 respectively. In the circuit the battery is ideal. A voltmeter of infinite resistance is connected in turn across R1 and R2 December [...]

A uniform wire of resistance R is shaped into a regular n−sided polygon (n is even), The equivalent resistance between any two corners can have. (i) the maximum value R/4 (ii) the minimum value R/n (iii) the minimum value R(n−1/n2) (iv) the minimum value R/n. A uniform wire of resistance R is shaped into a [...]

All the edges of a block with parallel faces are unequal. Its longest edge is twice its shortest edge. The ratio of the maximum to minimum resistance between parallel faces is. All the edges of a block with parallel faces are unequal. Its longest edge is twice its shortest edge. The ratio of the maximum [...]

n identical cells, each of emf ℰ and internal resistance r, are joined in series to form a closed circuit. One cell (A) is joined with reversed polarity. The potential difference across each cell, except A, is are joined in series to form a closed circuit. One cell (A) is joined with reversed polarity. The [...]

N identical cells, each emf E and internal resistance r are joined in series. Out of N cells, n cells are wrongly connected i.e., their terminals are connected in reverse of the required for series connection (n each emf E and internal resistance r are joined in series. Out of N cells n cells are [...]

The n rows each containing m cells in series are joined parallel. Maximum current is taken from this combination across an external resistance of 3Ω resistance. If the total number of cells used are 24 and internal resistance of each cell is 0.5Ω then The current i5 is December 1, 2020 Category: Cengage NEET by [...]
