Hi Sekhar,

Greetings to you!

Below is the sample code which I have tested in my org and it is working fine. Kindly modify the code as per your requirement.

Apex:

public class SaveAndNewC {
    
    @AuraEnabled
    public static Id saveDetails(Account regForm1){
        // DML operation to save Account Details   
        INSERT regForm1;
        return regForm1.Id; 
    }
}

Component:

<aura:component controller="SaveAndNewC"
                implements="lightning:isUrlAddressable,force:appHostable,flexipage:availableForAllPageTypes,flexipage:availableForRecordHome,force:hasRecordId,forceCommunity:availableForAllPageTypes,force:lightningQuickAction" access="global" >
    
    <aura:attribute name="PageHeading" type="String" default="Create Account"/>
    <aura:attribute name="RegForm" type="Account" default="{'sobjectType' : 'Account'}"/>
    
    <div class="slds-m-top--xx-large">
        <div class="slds-page-header">
            <div class="slds-align--absolute-center">
                <div class="slds-text-heading--large">       
                    {!v.PageHeading}
                </div>
            </div>
        </div>
    </div>
    <br/> <br/>
    
    <div class = "slds-size--3-of-8">
        <lightning:input label="Enter Account Name" name="accName" value="{!v.RegForm.Name}"/>
        <br/>
        <lightning:input label="Enter Phone" name="accPhone" value="{!v.RegForm.Phone}"/>
        <br/>
        <lightning:input label="Enter Website" name="accWebsite" value="{!v.RegForm.Website}"/>
        <br/>
        <lightning:button label="Submit" onclick="{!c.doSubmit}"/>
    </div>
</aura:component>

Controller:

({
    doSubmit : function(component, event, helper) {
        var regForm = component.get("v.RegForm");
        var action = component.get("c.saveDetails");
        action.setParams({regForm1  : regForm});
        action.setCallback(this, function(response) {
            var state = response.getState();          
            if (state === "SUCCESS") {
                var res = response.getReturnValue();
                component.set('v.RegForm','');
            }
            else if (state === "ERROR") {
                var errors = response.getError();
                if (errors) {
                    if (errors[0] && errors[0].message) {
                        console.log("Error message: " + 
                                    errors[0].message);
                    }
                } 
                else {
                    console.log(response.getReturnValue());
                }
            }
        });
        $A.enqueueAction(action);
    },
})

CSS:

.THIS {
    
}

.THIS.slds-size--3-of-8 {
    
    margin-left: 430px;
}

.THIS label.slds-form-element__label{
    
    font-size: 1.00rem;
    color: blue;
}

I hope it helps you.
