A flashlight has a resistance of 2.4 . What voltage is applied by the batteries if the current in the circuit is

hammer [34]

Answer : The voltage applied by the batteries is, 6.0 V

Solution : Given,

Resistance of flashlight = 2.4 ohm

Current in the circuit = 2.5 Ampere

Formula used :

$V=IR$

where,

V = applied voltage

I = current in the circuit

R = resistance of light

Now put all the given values in the above formula, we get

$V=(2.5A)\times (2.4ohm)=6volt=6V$

Therefore, the voltage applied by the batteries is, 6.0 V

The bonds S-S, O-H and Ca-Cl are, respectively, a) nonpolar covalent, polar covalent, ionic polar covalent, b)nonpolar covalent,

Brums [2.3K]

Answer:

nonpolar covalent, polar covalent, ionic

Explanation:

From the question ,

S - S Bond -

Both the atom are same , hence , making a non polar bond , because of no difference between the electronegativity of the atom ,

Hence , the S-S Bond is non polar covalent bond .

O-H bond -

The Oxygen atom is more electronegative than the hydrogen atom , so the bond is polar in nature .

And as the bond is formed by sharing ,

Therefore ,

O-H bond is polar covalent bond .

Ca-Cl bond -

Calcium is a metal , whereas , Chlorine is a non - metal , the bond is ionic in nature ,

Hence , Ca-Cl bond is ionic in nature .
