To determine the correct order of resistances \( R_1, R_2, R_3, \) and \( R_4 \) for a milliammeter, ammeter, voltmeter, and kilovoltmeter respectively, we can analyze the behavior of these instruments in terms of their resistance. ### Step-by-step Solution: 1. **Understanding the Instruments**: - A **milliammeter** (with resistance \( R_1 \)) is designed to measure small currents. - An **ammeter** (with resistance \( R_2 \)) is used to measure larger currents. - A **voltmeter** (with resistance \( R_3 \)) measures voltage across components. ...

A galvanometer is to be converted into a voltmeter and an ammeter successively by using either of two resistances R_1 and R_2 (R_1 gt R_2)

If the resistance R_(1) is increased how will the reading of the ammeter and voltmeter change

In the given circuit, the ratio of voltmeter reading to the ammeter reading is R' . If resistance of ammeter is RA and that of voltmeter RV , then

A voltmeter of resistance R_1 and an ammeter of resistance R_2 are connected in series across a battery oif negligible internal resistance. When as resistance R is connected in parallel to voltmeter reading of ammeter increases three times white that of voltmeter reduces to one third. Find R_1 and R_2 in terms of R .

Resistance value of an unknown resistor is calculated using the formula R=V/I where V and I be the readings of the voltmeter and the ammeter respectively. Consider the circuits below. The internal resistances of the voltmeter and the ammeter ( R_v and R_G respectively ) are finite and non zero. Let R_v and R_G be the calculated values in the two cases A and B respectively. If the resistance of voltmeter is R_v=1kOmega and that of ammeter is R_G=1Omega the magnitude of the percentage error in the measurement of R (the value of R is nearly 10Omega ) is:
